ICO vs IDO Launchaps

I have done the following observation:

IDOs, managed by a platform, are proposing a replacement for traditional self-managed ICOs. IDOs provide handy functionalities out of the box, as liquidity locking, vesting, creation and deployment of the token in a DEX, trust to the investors, KYC of the team, audited contracts....

However, this does not seen to come for free as IDOs force a number of restrictions in raising capital to the token issuer: limited time, 5% fee, link the softcap to the hardcap, as far as I can see the raised amounts is millions for ICOs and IDOs barely get the $200k, you cannot chain rounds for IDOs as you are pushed to the DEX after the IDO.... Startups raising large hardcaps looks to be still doing ICOs according to listings (eg icodrops).

So, I am confused and here are my questions:

* Why a higher simplicity in the process comes with such a big restrictions?

* Are ICOs dying or you think they will survive IDOs?

* Are IDOs ruining the capital raising experience?
